摘要: 结合亲核取代反应与硅氧烷水解和硅羟基缩合反应,制备了羧酸镉/二氧化硅复合材料。 通过硫化反应,实现了立方结构和六方结构硫化镉纳米粒子在复合材料中的原位制备。 复合材料中硫化镉纳米粒子的发射峰位在617 nm,属于红色荧光(三元色之一),硫化镉/二氧化硅复合材料在光学器件方面具有潜在的应用前景。

Abstract: The cadmium carboxylate/silica composite materials(CCSM) were prepared through the combined use of nucleophilic substitution, hydrolysis of siloxane, and condensation of silanol. The CdS nanoparticles of cubic and hexagonal structures were prepared in situ in CCSM by vulcanization. The emission peak of CdS nanoparticles in CCSM belongs to the red fluorescence at 672 nm(one of the three primary colors), suggesting that the CdS/silica composite materials have a potential application as optical devices.

Key words: Silica, CdS, composite materials, in situ, nanoparticles red fluorescence
